저는 한국어를 잘 못합니다. 죄송합니다

Well, I know how to say "I can't speak korean well": 한국의 잘 못해요. <This translates to 'Korean well can't speak'. & "I'm sorry": 미ㅑㄶ< This translates to 'sorry'. So to learn how to pronounce the characters you will need to reference to the Korean Alphabet. Use this link for the alphabet reference--- http://www.omniglot.com/writing/korean.htm
